Notes:

If two directions are given, the original Centers take the first
direction and the original Outsides take the second direction. If
only one direction is given, everybody takes that direction.

The Centers always pass Right shoulders even if the call is
Strut Left. The caller should say Left Strut Right|Left if a
Left shoulder pass is desired.

If your given direction is Right, then you must end as a
Beau (i.e., you want to end as if you are in a
Right-hand Tidal Wave); Similarly, if your given direction is
Left, you must end as a Belle.

Hint: The original Outsides should not move until the Centers have almost
completed their part of the call, so that sufficient space is available for the
Outsides to execute their part.
